In many road and airport projects in the Middle East, Polymer Modified Bitumen (PMB) is being specified by consultant. Although PMBs are not new in the paving world, Suppliers and Contractors in the region are being challenged in producing these specialty bitumen, designing asphalt mixtures, and constructing pavements with PMBs. This workshop will show you what are the most common methods of design of mixtures and compare the use of the Marshall design with the newly applied Superpave Mixture Design. It will also cover the main types of polymers and other additives used in modifying bitumen, and the key considerations for selecting them; what producers of PMBs and contractors using mixtures with PMB are worried about; and how to blend materials to achieve the required PMB Grades. The workshop will also explain how certain Bitumen modifications are changing Bitumen Content and affecting performance properties of mixtures.
